Re: changing the title of a histogram

In a macro you should call gPad->Update() before caling GetListOfPrimitives

From the ROOT prompt, I can use the ListOfPrimitives, and access the TPaveText of the title, but from a macro (e.g. the one attached) it does not work --> the title is not in the list of primitives of the pad. Any suggestion? Am I doing something wrong? Something I could change through gStyle, but it is not really what I would like to do. Moreover, I thought that the SetTitleAlign would have modified the alignment of the title, but if I change the parameter, it does not do what I expected. <testUpdate.C>
